Surgeries to correct congenital heart diseases are increasing in Brazil and worldwide. However, even with the advances in surgical techniques and perfusion, some cases, especially the more complex ones, can develop heart failure and death. A retrospective study of patients who underwent surgery for correction of congenital heart diseases with cardiopulmonary bypass (CPB) in a university tertiary-care hospital that died, showed infarction in different stages of evolution and scattered microcalcifications in the myocardium, even without coronary obstruction...

PURPOSE: Toll-like receptor 4 (TLR4) is a transmembrane receptor that mediates immune responses to exogenous and endogenous ligands. Previously, non-coding single nucleotide polymorphisms (SNPs) in the TLR4 gene were related to primary open angle glaucoma (POAG). This study was undertaken to investigate whether coding TLR4 Asp299Gly (rs4986790 A/G) and Thr399Ile (rs4986791 C/T) are associated with POAG in a Mexican population. METHODS: One hundred and eighty-seven unrelated Mexican patients with POAG (94 men and 95 women; mean age 66...

We investigated the effects of S-777469 (1-[[6-Ethyl-1-[4-fluorobenzyl]-5-methyl-2-oxo-1, 2-dihydropyridine-3-carbonyl]amino]-cyclohexanecarboxylic acid), a novel cannabinoid type 2 receptor (CB2) agonist, on 1-fluoro-2,4-dinitrobenzene (DNFB)-induced ear inflammation and mite antigen-induced dermatitis in mice. The oral administration of S-777469 significantly suppressed DNFB-induced ear swelling in a dose-dependent manner. In addition, S-777469 significantly alleviated mite antigen-induced atopic dermatitis-like skin lesions in NC/Nga mice...

BACKGROUND/AIMS: The endogenous retinoid 9-cis-retinoic acid has previously been shown to trigger apoptosis in a wide variety of cells including several tumor cells and has thus been suggested for the treatment of malignancy. Similar to apoptosis of nucleated cells, erythrocytes may enter suicidal erythrocyte death or eryptosis, which is characterized by cell shrinkage and cell membrane scrambling with phosphatidylserine translocation to the erythrocyte surface. Cellular mechanisms participating in the accomplishment of eryptosis include increase of cytosolic Ca2+ activity ([Ca2+]i) and formation of ceramide...

BACKGROUND/AIM: Accumulation of advanced glycation end products (AGEs) is a major cause of diabetes mellitus (DM) skin complications. Methylglyoxal (MGO), a reactive dicarbonyl compound, is a crucial intermediate of AGEs generation. N-acetyl-L-cysteine (NAC), an active ingredient of some medicines, can induce endogenous GSH and hydrogen sulfide generation, and set off a condensation reaction with MGO. However, there is rare evidence to show NAC can alleviate DM-induced skin injury through inhibition of AGEs generation or toxicity...

BACKGROUND: Emodin has anti-neoplastic activities on multiple tumors. However, the molecular mechanisms underlying this effect still remain to be fully understood. METHODS: Cell viability and cell cycle distribution were measured using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assays and flow cytometry, respectively. Cell invasion and migration were examined by transwell invasion and wound healing assays. Western blot analysis was performed to examine the phosphorylation and protein expression of AMP-activated protein kinase alpha (AMPKα), extracellular signaling-regulated kinase 1/2 (ERK1/2), peroxisome proliferators-activated receptor gamma (PPARγ), insulin-like growth factor (IGF) binding protein 1 (IGFBP1) and the transcription factor Sp1...

In this work, transgenic lines of suspension cultured cells of Vitis vinifera cv. Monastrell containing the plasmid pMOG800-sts have been obtained. The cell growth of these transgenic cell lines decreased slightly as compared to non-transgenic suspension cultured cells, while cell viability was not affected. In addition, the elicitation with cyclodextrins and methyl jasmonate enhanced the production of trans-resveratrol, observing the highest levels of this compound in sts-expressing transgenic Vitis suspension cultured cells with the sts expression cassette in the forwards orientation...

Previous research has found an association between a smaller cerebellar volume and higher levels of neuroticism. The steroid hormone testosterone reduces stress responses and the susceptibility to negative mood. Together with in vitro studies showing a positive effect of testosterone on cerebellar gray matter volumes, we set out to explore the role of testosterone in the relation between cerebellar gray matter and neuroticism. Structural magnetic resonance imaging scans were acquired, and indices of neurotic personality traits were assessed by administering the depression and anxiety scale of the revised NEO personality inventory and Gray's behavioural avoidance in one hundred and forty-nine healthy volunteers between 12 and 27 years of age...

Survival motor neuron (SMN) is a 38-kDa protein, whose deficiency in humans develops spinal muscular atrophy (SMA), an autosomal recessive neurodegenerative disease with muscular atrophy due to motor neuron death in the spinal cord. We now report that SMN prevents the activation of TRAF6 and IκB kinase (IKK) and thereby negatively regulates the NF-κB signaling processes. SMN physically interacted with TRAF6 and with each component of the IKK complex, IKK-α, IKK-β, and IKK-γ in BV2 microglia cells. Moreover, SMN1 inhibited the E3 ubiquitin ligase activity of TRAF6 as well as the kinase activity of IKK...

This study attempted at maximizing biomass and lipid accumulation in Chlorella vulgaris by supplementation of natural abscisic acid (ABA) or synthetic 2,4-dichlorophenoxyacetic acid (2,4-D) and 1-naphthaleneacetic acid (NAA) hormone analogs. Amongst three tested additives, NAA-treatment performed remarkable promoting effect on cell growth and lipid biosynthesis. The favorable lipid productivity (418.6mg/L/d) of NAA-treated cells showed 1.48 and 2.24 times more than that of 2,4-D and ABA. NAA-treatment also positively modified the proportions of saturated (C16:0 and C18:0) and monounsaturated fatty acids (C18:1) which were prone to high-quality biofuels-making...

Natural light cycles are important for synchronizing behavioral and physiological rhythms over varying time-periods in both plants and animals. An endogenous clock, regulated by positive and negative elements, interacting in feedback loops, control these rhythms. Many corals exhibit diel cycles of polyp expansion and contraction entrained by solar light patterns and monthly cycles of spawning or planulation that correspond to nocturnal lunar light cycles. However, despite considerable interest in studies of coral reproduction, there is currently not enough molecular information about the cellular pathways involved with synchronizing spawning/planulation in broadcast spawners and brooders...

Protein tyrosine kinase 6 (PTK6; also known as Brk) is closely related to the Src family kinases, but lacks a membrane-targeting myristoylation signal. Sublocalization of PTK6 at the plasma membrane enhances its oncogenic potential. To understand the mechanism(s) underlying the oncogenic property of plasma-membrane-associated PTK6, proteins phosphorylated by membrane-targeted myristoylated PTK6 (Myr-PTK6) were enriched and analyzed using a proteomics approach. Eps8 which was identified by this method is phosphorylated by Myr-PTK6 in HEK293 cells...

Almost all synthetic pathways for biofuel production are designed to require endogenous metabolites in glycolysis, such as phosphoenolpyruvate, pyruvate, and acetyl-CoA. However, such metabolites are also required for bacterial cell growth. To reduce the metabolic imbalance between cell growth and target chemical production, we previously constructed a metabolic toggle switch (MTS) as a conditional flux redirection tool controlling metabolic flux of TCA cycle toward isopropanol production. This approach succeeded to improve the isopropanol production titer and yield while ensuring sufficient cell growth...

Although it is well established that acute kidney injury (AKI) is a proinflammatory state, little is known about the endogenous counter-inflammatory response. IL-6 is traditionally considered a pro-inflammatory cytokine that is elevated in the serum in both human and murine AKI. However, IL-6 is known to have anti-inflammatory effects. Here we sought to investigate the role of IL-6 in the counter-inflammatory response after AKI, particularly in regard to the anti-inflammatory cytokine IL-10. Ischemic AKI was induced by bilateral renal pedicle clamping...

Degradation of the hybrid layer created in dentin by dentin adhesives is caused by enzyme activities present within the dentin matrix that destroy unprotected collagen fibrils. The aim of the present study was to evaluate the effect of a one-step self-etch adhesive system on dentinal matrix metalloproteinases 2 and 4 (MMP-2 and MMP-9, respectively) using in situ zymography and an enzymatic activity assay. The null hypothesis tested was that there are no differences in the activities of dentinal MMPs before and after treatment with a one-step adhesive system...

BACKGROUND: Cytochrome P4501A1 (CYP1A1) is a member of the cytochrome P450 gene family and plays an important role in the metabolism of exogenous and endogenous material. In recent research, it has been shown that its genetic polymorphisms are associated with many diseases. But the isoschizomers such as the BsrDI enzyme required for the detection of this polymorphism are expensive. METHODS: The study used an improved PCR-RFLP method with mismatched base for detection of the single-nucleotide polymorphism rs1048943...

Systemically administered opioids are among the most powerful analgesics for treating severe pain. Several negative side-effects (respiratory depression, addiction, nausea, confusion) and the risk of opioid-induced hyperalgesia accompany opioid administration. One other side effect is the potential of opioids to suppress the immune response and thereby to increase the vulnerability for infections. Several studies have investigated the link between opioids and immunosuppression in vitro, in vivo as well as in patients with divergent results: Exogenous opioids such as morphine and fentanyl can impair macrophage and natural killer cell as well as T cell function and weaken the gut barrier in vitro and in animal studies...

Reprogramming cell fates towards pluripotent stem cells and other cell types has revolutionized our understanding of cellular plasticity. During the last decade, transcription factors and microRNAs have become powerful reprogramming factors for modulating cell fates. Recently, many efforts are focused on reprogramming cell fates by non-viral and non-integrating chemical approaches. Small molecules not only are useful in generating desired cell types in vitro for various applications, such as disease modeling and cell-based transplantation, but also hold great promise to be further developed as drugs to stimulate patients' endogenous cells to repair and regenerate in vivo...

Diabetes is a complex, multifactorial group of metabolic diseases characterized by chronic hyperglycaemia due to pancreatic beta-cell dysfunction and/or loss. It is characterized by an asymptomatic and highly variable prodromic phase, which renders diabetes mellitus difficult to be predicted with sufficient accuracy. Despite several efforts in the identification and standardization of newly trustable. Biomarkers able to predict and follow-up diabetes and to specifically subtype its different forms, few of them have proven of clinical utility...
